Who should care
Users of ArcadeDB versions before 26.8.1, administrators of systems with ArcadeDB installed, security teams monitoring for authentication bypass vulnerabilities, and operators managing affected deployments should be aware of this vulnerability and take necessary actions to protect their systems. Additionally, vulnerability management teams and security teams should review and implement compensating controls for exposed systems while remediation is scheduled and verified. This may involve restricting access to port 27017 and monitoring for suspicious activity on the MongoDB wire-protocol plugin. Furthermore, asset inventory and configuration management teams may need to review and update their records to ensure accurate tracking of affected systems. IT teams responsible for change management and incident response should also be informed to prepare for potential remediation efforts. Lastly, source tracking and incident response teams should be prepared to verify and document evidence of vulnerability remediation. In terms of defensive priorities, the focus should be on implementing compensating controls, verifying affected scope, and ensuring that remediation efforts are properly tracked and documented. This may involve coordination with multiple teams, including security, IT, and development teams. The goal is to minimize potential impact and ensure that affected systems are properly secured. To achieve this, teams may need to review and update their incident response plans, change management processes, and vulnerability management procedures. By taking a proactive and coordinated approach, organizations can reduce the risk associated with this vulnerability and ensure the security of their systems. In addition to these efforts, teams should also consider implementing additional security controls, such as monitoring and detection systems, to help identify and respond to potential security incidents. By doing so, organizations can improve their overall security posture and reduce the likelihood of a successful attack. Overall, a comprehensive and coordinated approach is necessary to effectively address this vulnerability and protect against potential threats. This
Technical summary
ArcadeDB versions before 26.8.1 fail to enforce SASL authentication on data commands in the MongoDB wire-protocol plugin, allowing unauthenticated attackers to issue insert, find, update, delete, and create commands against any database by connecting to port 27017 without credentials. This vulnerability affects systems with ArcadeDB installed, particularly those with exposed MongoDB wire-protocol plugin.
Defensive priority
Authenticated attackers could issue insert, find, update, delete, and create commands against any database by connecting to port 27017 without credentials, indicating a critical vulnerability.
Recommended defensive actions
- Inventory and verify ArcadeDB versions, checking for version 26.8.1 or later.
- Implement compensating controls, such as restricting access to port 27017.
- Monitor for suspicious activity on the MongoDB wire-protocol plugin.
- Exception tracking and retest after vendor remediation.
- Review official advisory or CVE record to validate affected scope, severity, and vendor guidance.
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
